ABSTRACT
Theileria infected cell line was isolated from the prescapular lymph node of an adult crossbred cow. Molecular study confirmed this cell line of bovine lymphocyte has been transformed by the Theileria lestoquardi. This strain of T. lestoquardi designated Ka-6 and sheep were inoculated with this strain didn't show any clinical signs of theileriosis which shows the significance of this cell line to develop a tissue-culture vaccine against malignant ovine theileriosis. Contrary to accepted belief that the T. lestoquardi not capable of causing disease in cattle, the present study describes the first isolation and establishment of in vitro culture of T. lestoquardi-infected cell line from a naturally infected cow with typical singes of acute theileriosis.
ABSTRACT
INTRODUCTION: Internal hernia is a very rare cause of intestinal obstruction (0.2-0.9% of cases), associated with 45% mortality. A review of the literature revealed just eight reported cases of double omental hernia since 1950 of which our patient is the first case successfully treated laparoscopically. CASE PRESENTATION: We report on a 29-year-old man who presented with signs and symptoms of intestinal obstruction. The patient underwent emergent exploratory laparoscopy. This revealed herniation of a 20-cm jejunal loop through the gastrocolic ligament and reemergence through a defect in the gastrohepatic ligament. The strangulated loop was reduced with slight traction, and the defect was repaired. The patient was discharged from hospital in just 5 days' time, and after 6 months of follow-up, the general condition of the patient was normal. CONCLUSIONS: Laparoscopy is a good technique with minimal complications compared with laparotomy. As many cases are missed due to nonspecific signs and symptoms, an urgent laparoscopy or laparotomy is highly recommended in such a situation.

Objectives of this study were to test the cytokine gene expression in peripheral blood mononuclear cells (PBMCs) from cases with nonhealing and healing cutaneous leishmaniasis (CL) in response to in vitro stimulation of recombinant gp63 (rgp63) and soluble Leishmania antigen (SLA). Healing and nonhealing cases are, respectively, defined as recovered from disease and refractory to various treatments. To evaluate the type of immunological response, mRNA transcription level for interleukin (IL)-4, IL-10, IL-12 and interferon (IFN)-gamma were determined using semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) technique in PBMCs of these volunteers. The results clearly demonstrated a high level of IL-4 expression in nonhealing cases of CL and a low expression level of transcripts for IFN-gamma and IL-12. In contrast, a high level of IFN-gamma and IL-12 expression and a low level of IL-4 and IL-10 expression were detected in the healing cases. These findings not only support the balance of Th1/Th2 cytokines in the inducing predominant profile in healing and nonhealing cases, but it may also show the potential of rgp63 as a proper immunogen which might induce protective responses.

Theilerin was prepared and its total nitrogen was determined at level of 1 mg/ml. Seventy-two Holstein Friesian cattle recovered from acute theileriosis or vaccinated received 0.1 ml of theilerin intradermally at normal concentration of total nitrogen or other dilutions (1 / 10 and 1 / 100). Some 60(% of calves and 66.67% of milking cows receiving normal theilerin showed more than 1 mm increase in skin thickness at the site of inoculation (mean value of 1.86 mm for calves and 3.46 mm for milking cows). The pathological examination of the inoculation site showed infiltration of lymphocytes. No changes of general condition were observed in animals under study. The result indicated that the test is positive and could be used for checking Immunity in vaccinated animals.
